I'm sick and tired of 5 stacks, intentional or not, getting the better deal when it comes to ranking adjustments after the match.

You don't 5 stack by chance. You chose to do that. So your rating should take the hit.

It's insane that you can group with people of widely different skill ratings to lose very little rating but if you win you gain a lot.

Because not only are the 1k accounts often just smurfs or troll accounts but it also feels ass when you solo queue, run into 5 stack and gaining f*** all points.

The next match you play is vs randoms, you lose and now you're down points because you lose a lot more than you gained last match. All while effectively being 1-1.

And no, my history is not cooked. You can see that in the 2nd screenshot. The highlighted matches are vs 5 stacks.
